Description

  The present invention belongs to a technical field related to a hand-held unicycle used for carrying luggage in agricultural work or civil engineering work.

  Generally, a hand-held unicycle has a structure in which a loading tray on which a load is placed is mounted on a frame on which a single wheel is supported. Therefore, there is a characteristic that it is difficult to balance during the transportation of the load and the load collapses easily. For this reason, there is a demand for the development of a hand-held unicycle that can prevent the collapse of the load during the transportation of the load.

  2. Description of the Related Art Conventionally, as a hand-held unicycle oriented to prevent the collapse of a load during transportation of a load, for example, the one described in Patent Document 1 is known.

  Patent Document 1 describes a hand-held unicycle that includes a frame that is supported by a single wheel at the bottom and a load carrier that supports a load at the top, and that is provided with a rope hook for hanging a rope that binds the load to the frame. ing.

  The hand-wheeled unicycle according to Patent Literature 1 is intended to prevent the collapse of the load during transportation of the load by fixing the load placed on the frame by hanging the rope on the rope hanging portion.

JP-A-9-71243

  The hand-wheeled unicycle according to Patent Document 1 has a structure in which a loading tray on which a load is placed is not mounted on a frame, and therefore cannot be applied to a hand-held unicycle equipped with a loading plate as it is.

  The present invention has been made in view of such problems, and it is an object of the present invention to provide a hand-held unicycle having a structure equipped with a loading tray and capable of preventing collapse of the load during transportation of the load. .

  In order to solve the above-mentioned problems, the hand-wheeled unicycle according to the present invention employs means described in each claim of the utility model registration request.

  That is, according to claim 1, in the hand-held unicycle equipped with a rope hanging portion on which a luggage tray for placing a load is mounted on a frame on which a single wheel is supported and a rope for fixing the luggage is hung, the rope hanging portion Is formed in a ring shape and fixed to the lower part of the periphery of the cargo tray, and the rope has a hook attached to the rope hooking portion at the end of the elongated main body.

  In this means, the rope hook is fixed to the lower part of the peripheral edge of the cargo tray that does not interfere with the load and is formed into a ring shape that is easy to hook the rope, and it is easy to hook the ring-shaped rope hook at the end of the main body of the rope. By attaching the hook, the load placed on the cargo tray can be fixed by hanging the rope even if the upper surface of the cargo tray has a wide opening.

  According to a second aspect of the present invention, in the hand-held unicycle according to the first aspect, the rope hooking portion is fixed to a bar-shaped bar fixed to the lower part of the peripheral edge of the cargo tray with a gap.

  With this means, the tension stress of the rope that fixes the load is concentrated on a part of the load plate made of thin plate material by interposing the bar-shaped bar between the rope hook and the load plate. Can be avoided.

  According to a third aspect of the present invention, in the hand-held unicycle according to the first or second aspect, the rope has elastic elasticity in the main body.

  With this means, the rope body has elastic elasticity, so that even different loads can be bound with a certain level of tensile force.

  The hand-operated unicycle according to the present invention is formed in a ring shape in which the rope hook portion is fixed to the lower part of the peripheral edge of the cargo tray that does not interfere with the load and is easy to hook the rope. Since the hook that makes it easy to hang on the part can be attached, the load placed on the loading plate can be fixed by hanging the rope even if it has a loading plate with a wide upper surface. Thus, there is an effect of preventing the collapse of the load during the transportation of the load.

  Further, as claimed in claim 2, by inserting a bar-shaped bar between the rope hooking portion and the cargo tray, the tensile stress of the rope fixing the cargo to a part of the cargo tray made of a thin plate material is reduced. Since concentration can be avoided, there is an effect that deformation of the cargo tray can be prevented even if the rope is strongly bound to the load.

  Further, as claimed in claim 3, since the rope body has elastic elasticity, it is possible to bind even a load of different sizes with a certain degree of tension, so a large number of ropes having different lengths are prepared. The effect is no longer necessary.

It is a perspective view of the form for carrying out the hand-held unicycle concerning the present invention. FIG. 2 is an enlarged vertical sectional view of a main part in the use state of FIG. 1. It is a top view which shows the example of arrangement | positioning of the rope in the use condition of FIG.

  EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing the hand-held unicycle based on this invention is demonstrated based on drawing.

  In this embodiment, a shallow type is shown.

  This form includes a frame 1, a wheel 2, a loading tray 3, a bar 4, a rope hooking portion 5 and a rope 6.

  The frame 1 is provided with a wheel receiver 11 that rotatably supports the wheel 2 at the front part, a handle 12 for hand pushing is provided at the rear part, and an auxiliary leg 13 that prevents a fall when not running is provided in the middle part. It has been.

  The wheel 2 is composed of a single wheel that is rotatably supported by the wheel receiver 11 of the frame 1.

  The cargo tray 3 is formed on a shallow bottom having a wide upper surface and is fixed on the frame 1. As shown in detail in FIG. 2, the peripheral edge 31 of the cargo tray 3 made of a thin plate material is reinforced with a structure wound around a core metal 32.

  The bar 4 is formed in a bar shape, and is fixed to the lower portion of the peripheral edge 31 of the cargo tray 3 by welding or the like in a fashion along the peripheral edge 31. The bars 4 are fixed to the front, rear, left and right of the cargo tray 3, respectively.

  The rope hooking portion 5 is fixed to a bar 4 which is formed in a ring shape (arc shape) and fixed to the front, rear, left and right of the cargo tray 3. A total of eight rope hooks 5, two for each bar 4, are provided so as not to protrude too much to the outside of the peripheral edge 31 of the cargo tray 3.

  The rope 6 has U-shaped hooks 62 that can be attached to and detached from the rope hooking portion 5 at both ends of a main body portion 61 made of a long rubber band having elastic elasticity.

  According to this embodiment, the load is placed on the cargo tray 3 in a state where the wheels 2 and the auxiliary legs 13 of the frame 1 are grounded.

  Then, one hook 62 of the rope 6 is hung on one rope hanging portion 5 to bind the load, and the other hook 62 of the rope 6 is hung on the other one rope hanging portion 5 to fix the load. Can do. Note that the hanging direction of the rope 6 can be freely set by selecting the rope hanging portion 5 to be hung according to the size and shape of the load, as shown in FIG.

  In this rope hanging, since the rope hanging portion 5 is ring-shaped and the hook 62 of the rope 6 is U-shaped, the work can be easily and reliably performed. Unintentional withdrawal can also be avoided. Further, since the rope hooking portion 5 is provided not on the frame 1 but on the cargo tray 3, it is not necessary to hang the rope 6 unnecessarily. Moreover, since the main-body part 61 of the rope 6 has elastic elasticity, even a load having different sizes can be bound with a certain tensile force. Therefore, it is not necessary to prepare a large number of ropes 6 having different lengths. Further, by inserting a bar-shaped bar 4 between the rope hooking portion 5 and the loading tray 3, the tensile stress of the rope 6 fixing the load to a part of the loading tray 3 made of a thin plate material is reduced. You can avoid concentrating. Therefore, even if the rope 6 is strongly tied to the load, the deformation of the loading tray 3 can be prevented.

  After the luggage is fixed to the loading tray 3, the vehicle travels by grasping the handle 12 of the frame 1 and lifting the auxiliary leg 13 from the ground.

  At this time, since the load placed on the loading tray 3 is firmly fixed by the rope 6, the load does not collapse.

  Further, since the rope hooking portion 5 is provided so as not to protrude so much outside the peripheral edge 31 of the cargo tray 3, the rope hooking portion 5 is not caught on a person or an object during traveling, and safety is ensured. The

  As described above, one or three or more rope hooks 5 can be fixed to each bar 4 in addition to the illustrated form.

  Furthermore, the main body 61 of the rope 6 can have elastic stretchability other than the rubber band.

  Furthermore, the hook 62 of the rope 6 can be formed in a shape other than the U-shape.
